Abstract

The microwave absorbing characteristics of basic cobalt carbonate, cobalt oxide (Co 3O 4), and the mixture of basic cobalt carbonate and cobalt oxide were investigated by means of microwave cavity perturbation, their temperature increasing curves were measured, and their ability to absorb microwave energy was also assessed based on the temperature increasing behavior of the material exposed to microwave field. Analyses of spectrum attenuation and relative frequency shift show that basic cobalt carbonate has weak capability to absorb microwave energy, while cobalt oxide has very strong capability to absorb microwave energy. It is feasible to thermally decompose basic cobalt carbonate though addition of small amount of cobalt oxide in microwave fields. The capability to absorb microwave energy of sample increases with an increase in mixing ratio of Co 3O 4.
